Arriving at the weekend
The Palstar quality and features that Hams worldwide have come to expect is now available in a compact, low power affordably priced tuner, the AT-500 600 watt antenna tuner.
Covering 160 to 6 Meters with a power rating of up to 600 watts PEP, the AT-500 features a differential tuning capacitor with 2 stators and 1 rotor, a precision ceramic body roller inductor, and a 4:1 ferrite current balun for balanced line feeds.
The AT-500 utilizes only 2 controls to operate for tuning, providing maximum ease of use in a manual tuner. A small-sized roller inductor operates all the way up to 6 m, while a relay-switched add-on inductor allows 160 m operation.
Also included is Pastar’s Active Peak and Peak Hold dual cross-needle metering as in the popular PM2000A wattmeter and 11ga. .090″ thick chem-film treated aluminum metalwork and durable powder coated finish. The AT-1500 is a tuner that will last a lifetime.
